01: Photosynthesis take place in the chloroplast of a plant cell.

02: The process of photosynthesis is also known as carbon assimilation.

03: One molecule of glucose contains about 686 K calories.

04: Raw material for this process are as follows

  • Water
  • CO2

05: Hales explained the relationship between sunlight and leaves in 1727 for the first time.

17: The other components of the photosytem II are as follows

  • Chlorophyll a 660
  • Chlorophyll a 670
  • Chlorophyll b
  • Phycobilins

20: In an oxygenic Photosynthesis, water is used as the electron donor.

22: Types of light dependent reactions are as follows

  • Cyclic
  • Non-cyclic

23: LHC stands for Light Harvesting Complex

25: Light-dependent reactions take place on the thylakoid membranes

Light and dark reactions

26: Hill and Bendall proposed ‘Z-Scheme’.

27: The products of light reaction are as follows

  • NADPH
  • ATP
  • O2

28: RuBisCO is the precursor of the Calvin cycle.

30: In Dark reaction or Calvin cycle, 18 ATP and 12 NADPH are consumed in the production of 1 glucose molecule.
